ecreased value of the peak current input to traction vehicles
from substations ;
-Capture of a considerable (40 – 50%) part of energy to be
returned to the contact line for the period of braking;
-Reduction in line voltage fluctuations.
-Energy storages installed on long no-load run routes must:
-Reduce the values of line voltage drop for the period of
intensive current consumption by the vehicles for the startup
phase;
-Capture the entire vehicle braking energy;
-Reduce the load on power units and traction sub-stations.
Installation of supercapacitor energy storages featuring
useful energy of ~2MJ (10F, 800V) ensures the economies
of about 50KWh electric energy per one hour.
Electrotechnical Institute has designed a supercapacitor
energy storage system to be mounted in a container and is
testing the model on a selected tramway line in Elbląg.
In the case of sub-stations, the energy storage may be
designed as a modular model with its units adapted to the
sub-station power capacity. Production of a double-module
(2x10F, 800V) system for Gdynia-based sub-station is in
progress.

Patent no. Short Patent MD206, 2010
SOLUTION: We propose an installation for dehydration
of alcohol consisting of: concentration column, column of
dehydration, dephlegmator, condenser, refrigerant,
Description
dehydration agent reservoir, dehydrated ethyl alcohol
reservoir, characterized in that the concentration column
has 45 trays, dehydration column has 52 trays, and for
regeneration of dehydration agent (propylene glycol) an
installation working in vacuum is used.
ADVANTAGES: Production of bioethanol (dehydrated
ethyl alcohol) can be organized in localities directly at
enterprises, producing food rectified ethyl alcohol in ethyl
alcohol dehydration installations using as dehydration
